Nurmagomedov took his record to a perfect 27-0 by battering McGregor at T-Mobile Arena and taking full control with his seemingly unstoppable wrestling ability, recording a fourth-round submission victory when McGregor tapped out after being caught in a rear naked choke.

LAS VEGAS – Khabib Nurmagomedov submitted Conor McGregor in the fourth round Saturday in their lightweight title fight at UFC 229, then leaped over the top of the cage to go after McGregor teammate Dillon Danis, a Bellator fighter.

The submission came at 3:03 of the fourth.

A huge scrum of people got together near the Octagon, including police officers, members of both teams and members of the Nevada Athletic Commission. It was against the fence where fans were seated. Nurmagomedov and Danis exchanged punches as people attempted to separate them.

After the scrum was broken up after about 10 minutes, UFC president Dana White said to Nurmagomedov in the cage, “People are going to get arrested tonight.” Nurmagomedov responded, “Put me in jail. No problem.”

White said to Nurmagomedov, “This is what I believe: If I put this belt on you, everybody’s going to start throwing s–t into the Octagon.”

Not long after Nurmagomedov went after Danis, a man in a black T-shirt got into the Octagon and threw a least one punch at McGregor. Then, a man in a red T-shirt jumped over the cage and landed four punches on McGregor. It did not appear that McGregor ever left the cage.

It made the most hyped fight in UFC history somewhat anticlimactic. Nurmagomedov controlled the bout and had McGregor on his back for much of it. McGregor had a better third round and kept the fight standing, but never landed a significant punch.

In the fourth, Nurmagomedov took McGregor down and worked to get his back. After he got his back, he quickly put on a rear-naked choke and forced a quick tap.

When Nurmagomedov released the hold, he got up and immediately raced to the side of the cage, leaped over and appeared to go after Danis.

Nurmagomedov was pulled from the scrum after about five minutes and escorted to the back. McGregor did not appear to get involved. He was removed from the Octagon with a heavy police and security presence after about 15 minutes.
